Abstract

A multiparty simultaneous communication system includes at least one first user premises equipment (A) and second and third user premises equipments (B,C), the first user premises equipment being connectable with the second and third user premises equipments via a network (N), to which the first user premises equipment is subscribed. The system includes a first simultaneous communication device (MA), mounted in the first user premises equipment (A), capable of simultaneously communicating two kinds of information via a single communication line (LA), an equipment for simultaneous communication service (5) located inside or outside of the network, and at least one second simultaneous communication device (S1), mounted in the equipment for simultaneous communication service, capable of simultaneously communicating two kinds of information via a single communication line. The equipment for simultaneous communication service (S) controls the at least one second simultaneous communication device (51 connected to the first simultaneous communication device (MA) via a single communication line (LA) so that the first user premises equipment (A) can simultaneously communicate with the second and third user premises equipments (B,C).
